' A This invention pertains to the general class of'machines adapted forthe manufacture of paperarticles, and particularly tok the class ofperforating machines. An objectof applicants invention -is to provide aperforating machine whereby the handling of the material is reduced to aminimum. f

. A further object of applicants invention is thefproduction of a devicewhereby material Y may be perforated in a plurality of directions.

Y A further object of applicants invention is the production of aperforating machine simple and durable in construction, of asmall numberof parts, economical in operation, fool-proof and of high efficiency.

' A particular objectof applicants .invention is the production ofa-perforating machine wherein sheets of paper are perforated in aplurality of directions without rehandling of the paper. 4

A further object of applicants invention is the production of v aperforating machine 'wherein particular portions of the paper are`perfo-rated leaving other portions imperforate, said p'erforate andimperforate portions occurring at regular intervals.

. As faras applicant is aware devices n ow on the market for the purposeof perforating 'paper require the paper to lbe `re-handled through themachine in order to procure perforations'in more than one direction.Furthermore to'applicantsknowledge these mafchines'a're not capable ofperforating paperor other material in more than one direction, V leavingspaces imperforate. 4 Y

' In the form of the invention illustrated 'in the drawings a machine isprovided forfthe perforation of bank checks, stamps and various similararticles.` The checks are made up in book form. In the particular formshown the finished book would have three checks per page.`,'I`he,margins of the checks properex Vcept those which form a part ofthe page margin', are perforated in orderrthat they may be r readilytorn from the book. The check stubs,

however, are left imperforateand are intended to be leftbound in thebook. During the perforating operation several pages of the `finishedbook form one large sheet. In the sheet shown Iin-Fig.v 11 .there aretwelveof the means separating the perforating means VVata particularposition of the cam. In the these smaller sheets or pages which appearin the finished book. It is apparent, therefore, that during theperforating operation it is necessary when perforating in a longitudinaldirection to separate the perforating means at '55 regular intervals inorder to leave the space designed for the check stub imperforate.Furthermore, itis readily apparent that the sheet of paper must be timedwith respect to in order that the Ldesired portions of the sheet areperforated and other portions of the sheet left imperforate. In otherwords, the sheet of paper must start forward onv its way toward theperforating cutters at a particular position of the-means provided toseparate said cutters. c Y

In applicants device in the preferred embodimentthe perforating cuttersare separated by means of a cam. A stop for the paper is provided, whichstop is spaced from the perforating cutters at a predetermined position.The stop vis operatively connected lwithsaid cam and is removedregularly particular embodiment shown the stop is removedat the samektime that the cam spreads the perforating rolls. At the same time thatthe stop is removed a roller above the sheet is lowered, said rollerbeing opposite a com'- Y plementary roller below the sheet. Both ofthese rollers are power-driven and when the upper roller comes inContact with the sheet of paper thepaper moves forward. The removal ofthe stop and the dropping 0f the roller is simultaneous and occurs atregular intervals. This locates the sheet of paper definitely withrespect to the perforating cut,-

ters,` thus permitting definite portions ofthe paper to be perforatedand other portions to 0 be left imperforate.

Furthermore in orderto obviate re-handling of the sheet of paper inorder tolobtain perforation in avvertical direction (with -respect tothefinishedrbook) applicant pro- '95 has been aligned in, a particularposition. The sheet of paper is conveyed from the first perforatingcutters in the preferred embodiment by a series of belt conveyors. Aplurality of stops are provided in the path of the sheet. 'Each stop iscomposed of an electric switch which closes Vwhen contacted by theforward traveling edge of said paper. When all of the contacts areclosed a solenoid is energized which brings together two rolls whichcontact a side edge of the sheet. Both of these rolls are power-driven.In this manner the direction of the sheet is changed and the sheet isperforated a second time preferably at right angles to the firstperforation.

Many other objects and advantages of the construction herein shown anddescribed will vbe obvious to those skilled in the art from thedisclosure herein given. f Y a To this end my invention consists in thenovel construction, arrangement andcombination of parts herein shown'and described, and more particularly pointed out in the claims.

-is for the convenience of the operator in hanare attachedtomembers 18.However, a

plate 8 is in approximately the same plane as platform 4. Directly aboveroller 7 and normally in contact therewith is roller 10 suitably Yjournaled in frame 3.

Directly above roller 6 is roller 11 mounted upon movable journals, thelpurpose of which will be hereinafter set forth. Adjacent roller 7 isshaft 12,V upon which are slidably mount- Ved a plurality of perforatingcutters 13. The `upper surfaces of cutters 13are in alignment with theuppery surfaces of rollers 6 and .7. Between cutters 13' and roller 7 is4located plate 14 upon aA suitable support. Plate 14 is located between:roller 7 and cutters 13 inla manner similar lto the location of plate8, the purpose of which Ais to provide a continuous path between therollers for the material passing through the machine. Aboveeachgperforating `cutter 13 isa complementary perforating ycutter 16slidably mounted on shaft 17. Shaft 17Visrj ournaledat its ends inlevers 18, said levers 18 are journaled on trunnions 19 attached to theinner sides of frame 3. Levers 18, however, may be .pivotally mounted-by.anysuitable means. f Levers 18 at their ends opposite from those whichsupport shaft 17, supporti roller 11.-'1At7the end ofeach lever'f18adjacent therollerll is formeda projectionQO to which is attached oneend of a lever 21. Each lever 21 issupported at22 by suitablefm'eans-onthe inner-side of frame 3. Levers 21 are'also attached to and supportstop support: 23 'which extends transversely of the machine, and betweenrollers 10 and 11'. At the bottomfof'stop support 23 are legs 24 (seeFigs.'7 and 8): Stop 25 is provided `wijth a, plurality oflmembers 26vwhichare provided with"rectan gular.recesses 27 into which fit legs 24.*Members26` are also provided with slotsi28. Members 26are secured tothe`legs24 by means of suitable-pins 29 or Vother means, thus' allowingfor relative slidto theV bottom end of followers 32.k Followers guidemay be furnished'for followers 32, in which case itis pivotedto memberl.

4,Cam 30l when in voperation thus transmits a `rocking movement-to`lever 118, together with an up and down movement to shaft 17. Oppositeeach cutter 16 is a stripping mechanism 33 which straddles roller 16 at35. Stripper 33 is preferably of resilient terial, and strips thematerial from cutter 16 should same have a tendency to follow the cutterafter being perforated. Each member 33 is attached to a sliding bracket34. Sliding brackets 34 are attached to cross support 35 which issecured to the sides of frames 3 by means of brackets 36. Each bracket34 is secured to cross support 35 by means of a dove-tailed constructionas clearly shown in Fig. 4, which permitseach bracket 34 to slidesideways on support 35. Each bracket 34 is secured in position by a setscrew 37. To the bottom end of each bracket 34 ispivoted one end of alink 38.v On the other end of each link 38 is journaled a smoothingroller 39. Adjacent perforating cutters 13 and in the path of thematerial is roller 40. Between roller and cutters 13 is a suitable plate41 located similar to plates 8 and 14. Rollers 39 rest on top of roller40. Each roller 39 is resiliently held in contact with roller 40 bymeans of a spring 42. The purpose of the rollers 39 is to smooth out theperforations after the paper leaves the perforation cut* ters. Adjacentroller 40 and in line therewith is a roller 43. Between roller 40 androller 43 is located a suitable plate 44 located `between the rollerssimilar to the location of plates 8, 14 and 41. Passing over roller 43are belts 45. At 46 in Fig. 1 is clearly illustrated a gear train fordriving the various rollers mounted in the frame 3. The arrangement ofthese gears will be clearly understood by persons skilled in the art.

Referring now to Fig. 2, 47 is a roller journaled at its ends in thesides of frame 1. Belts pass over the roller 47. 48 is a roller with oneend journaled in the side of frame 1 and with its other end journaled inthe bearing 49. Bearing 49 is mounted on the member 50 of frame 1.Passing over rollers 48 and 47 are belts 51. 52 is a roller with one end53 journaled in the end of frame 1 and with its other end 54 ournaled inthe bracket 55. Bracket 55 is secured to the side of frame 2 by bolts56. Passing over rollers 48 and 52 are belts 57. It is clearly seen thatbelts 45, 51 and 57 form a continuous conveyor. AMounted on the frame 1and betweenbelts 57 are stops 58. Stops 58 comprise an upright standard59 (see Fig. 9) secured to the frame 1 by suitable bolts 60 or othermeans. The upper end of stop 58 comprises an electric switch which isformed as follows: 61 is a spacing member with a hollow bore throughwhich bolt 62 passes. Bolt 62 also passes through standard 59.Intermediate the head of the bolt and the member 61 is a resilientconducting member 63. Bolt 62 is held in place by burr 64 which contactselectrical connection ,65 which fits over bolt 62.

At the bottom of member 63 is a contact 66 which is opposite a similarcontact 67 normally forming therewith a gap 68. Contact 67 is mounted onthe standard 59 by means of al bolt-like member 69 integral therewithand spa'ced from the standard 59 by means of member 70. rlhe end ofmember 69 is threaded anda burr 71 provided therefor. An electricalconnection 72 lits over member 69 and the entire assembly securely heldto the standard 59 by meansof the burr 7l. In the preferred embodimentof the invention, standard 59 is preferably of insulating material.-l-lowever, any form of construction may beemployed such'that contacts66 and 67 and the leads thereto are normally insulated from each other.lt is readily seen that an electrical contact is established by pressingthe member 63, thus bringing contacts 66 and 67 together.

Motion is transmitted to rollers 47, 48 and 52 from roller 43 by meansof a belt train comprising belts 73, 74 and 75. Stops 58 project intothe path of the material on belts 57 such that the material will contactmember 63 of each stop 58 upon coming to the end of its path, thusclosing the electrical circuit through the stops 58. l preferablyprovide a plurality of stops in order that the paper will align itself.The stops are connected in series electrically and it is readilyunderstood that a complete electrical circuit is not effected until thematerial is in contact with all of the stops.

Mounted in the sides of frame 2 and parallel with belts 57 and 51 isroller 76 (see Fig. 5). Roller 76 is so mounted that it will contact theside edge of thepaper as it travels toward stops 58. Mounted aboveroller 76 is roller 77. The ends of roller 77 are journaled in slidingmembers 78 and 7 8. Mem bers 7 8 and 78 are slotted as shown at- 79 and.79 (see Figs. 5 and 13) through which the supporting ends of roller 76project. The supporting ends of roller 76 are j ournaled in the sides offrame 2. Members 78 and 78 are additionally slotted as shown at 80 and80. Within these slots project spring supporting brackets 81 and 81,respectively, formed integral with the sides of frame 2g as shownclearly in Fig. 12. Mounted between the upper ends o-f slots 80 and 80and brackets 81 and 8l are springs 82 and 82, respectively. Springs 82and 82 are compression springs and normally hold roller 77 upward out ofcontact with roller 76. At the bottom of members 78 and 7 8 are crosspieces 83 to which are secured cores 84. Cores 84 form a part ofsolenoids 85 and move along the longitudinal center line thereof tooperate members 78 and 78 as will be hereinafter set forth. Solenoids 85are suitably mounted upon member 86 of frame 2. The electrical circuitthrough solenoids 85 is connected in series with stops58 through asource of electrical energy, not shown, such that when all .f 7 6 is aplate 89. Adjacent roller 76 is roller 90 journaled in the sides offrame 2. Above roller 90 is a complementary roller 91 also journaled inthevsides of frame 2. Between roller 90 and stop 87 is a suitable plate92. Adjacent rollers 90 and 91 and mounted on the shafts 93 and 94.-,respectively, are a plurality of perforatinc cutters 95 and 96,respectively. Between perfo-rating cutters 95 and roller 90 is a plate97. Cutters 95 and 96 are slidably mounted upon shafts 93 and 94,rcspectively, and are secured in position by set screws 99. Mountedcross-wise on frame 2 and adjacent rollers 96is abrack-etsupport 100upon which are slidably mounted brackets 101 which form therewith adove-tailed connection shown clearly at 102. Brackets 101 are held inposition by set screws 103. At the bottom of each bracket 101 ispivotally mounted a link 104. At the other end of each link 104 ismounted a roller 105. Adjacent cutters 95 and in line .therewith is aroller 106. Roller 106 is j-ou-rnaled in the sides of frame 2. Rollers105 are directly above roller 106 and each is held normally in contacttherewith by a spring 107 mounted about the pivotal connection betweeneach link -1, and each bracket 101. The purpose of rollers 105 is tosmooth out the perforations after the paper leaves perforating cutters95 and 96. Between cutters 95 and roller 106 is a plate 108. MountedVupon each bracket 101 is aresilient member 11.0. Each resilient member110 straddles a cutter 96 at 112. The purpose of the resilient members110 is that of stripping from cutters 96 material that has al tendencyto follow the cutter. The operation of the stripper will be readilyapparent to persons skilled in the art. Tab-le or plate 113 may beplaced adjacent roller 106 to receive the material as it leaves, themachine. In Fig. 3 is clearly shown a gear train for the purpose ofdriving the rollers and cutter shafts 93 and 94 journaled in the sides`of fra-me 2.

ReferringnowV to the upper perforating cutter shown in Fig. 6, 115represents a collar reduced at one end to form a shoulder 116, saidreduced portion being threaded as shown at 117 accommodating aninternally threaded collar 118. Collars 115 and 118 secure therebetweenthe members composing an upper perforatingcutter (either 16er 96)composed of disk-like side members 119 and central member 120. Member120 has formed upon its peripheral edge projections 121 which, togetherwith the complementary space'125 in the lower `perforatingcutter, form adie. |The lower perforating cutters 13-and 95 both being similar are`secured to their respective shafts 12 and 93'by. means similar to thatjust described forA the .upper perforating cutters16 andv96. The sidedisks 122, however, are formed with apertures 123 in order to allow forthe escape of the waste material pressed-frein the paper during theperforating operation. Central disk 124 is merely a spacer. Members 121press small portions of material from the paper going through theperforating cuttersthereby'forming the' perforations. Shaft 93 uponwhich are mounted perforating cutters 95 projects through the frame 2and connects to lthe shaft 126 by means of a sleeve 127. Shaft 126 is journaled in brackets 128 on the frame 3. Shaft 12 eX- tends through theside of frame 1 and has attached thereto, bevel gear 129. Shaft 126 hasattached at one end thereof, bevel pinion 130 which meshes with ringgear 129.l Shafts 12 and 93 are thereby operatively connected. Power isfurnished to the perforating machine by means of a pulley 131 on theother end of shaft 12. The operation of the device is as follows: e

The sheet of paper is placed against the stop and guide strip 137cmtable 4. When cam rotates such as to raise shaft 17 and therewithperforating cuttersv16 andtherewith the inner ends of levers 18, roller11 being mounted on the other ends of levers 18, is lowered into contactwith the paper and stop 25 is simultaneously elevated by means of levers21. The paper is thusrmlyengaged between rollers 6 and '1 1 andmovesforward. Stop 25 is spaced from the perforating cutters at apredetermined distance such thatthe edge of the paper V just reaches theperforating cutters 16 as the cam lowers the cutters 16. Rollers 7 and10 cooperate in advancing the paper intothe perforating cutters. Thepaper having reached the perforating cutters just as the cam has closedsame, the paper will be perforated until the raised part of the 'camagain raises the shaft 17. This latter action leaves a spaceunperforated. When the cam again lowers cutters 16, the paper is againperforated. The unperforated spaces are repeated when the cam againraises cutters 16 on shaft 17. Perforated and unperforated rspaces arethus formed in the paper. The number of per-forated and unperforatedspaces in one sheet depends upon the length ofthesheet. In the sheetshown ink Fig. 11, 132 is'the advancing edge. The perforationsy startimmediately atthe advancing edge.- Three alternate perforated andunperforated spaces are formed in the sheet shown. The sheet shown is36" square. are 8 long leaving unperforated .spaces of 4 in width. Thesheet shown inF ig. 11

The perforated linesv will be cut along `the imaginary lines 133 bysuitable means and each one of the sections thus formed willbe'cuttransversely along imaginary lines indicated by i arrows 134However, before the sheet shown in Fig.. 11 is cut as thus indicated,sameis perforated in the opposite directionalong lines 135. ,As thepaper leaves perforating cutters 13 and 16, the perforated portions aresmoothed out by means of rollers 39 and 4() and the paper delivered tobelts 45.. Belts 45deliver the paperto belts 51. Belts 51 deliver thepaper to belts 57 which cause the leading edge of the paper to abutstops 58. The side edge of the paper passesthrough slot 135 in frame 2(seeF ig. 12) and slot 136` in sliding member 7 8 and is engagedbyroller 76, but is held from traveling further in a sidewise direcbothstops 58 and closes the contacts thereof, the electrical circuit throughthe solenoids 85 is closed. The cores 84 of the solenoids 85 `are drawndownward into the solenoids'thus pullingroller 77 downward and intocontact with the top of the paper. Stop 87yis simultaneously moved withthe downward movement of roller 77, inasmuch as the brackets 88 whichsupport stop 87 are attached to menibers 78 and 78. The'paper is drawnoff sideways and advanced through the perforating cutters 95 and -96with the cooperation of rollers 90 and 91. Rollers 105 and roller 106.serve to smooth out the portions that have been perforated. Theelectrical current is broken as soon as the paper disengages onestop 58and roller 77 returns to its original position. Brackets 81 and 81 limitthe upward movement of sliding members 78 and 7 8. kThe paperwillbeengaged by rollers 90 and 91 before the kelectrical cir 'cuit isbroken.

'that stop 25 will 'touch the top of the ma terial under it except whenshaft 1-'7 is elevated. However, due to the small weight of the partsame does not havea tendency to retard the movement of the material intothe machine.

Cams may be 'of the adjustable type whereby any series of lengths ofperforated and unperforated portions may be obtained. Rollers -11 and 77 although on movable journals are driven at all times. The slight upand down movement is not suflicient to disengage their respective gears.i

This invention has been described as applied to the manufacture of bankchecks;` however, it is obvious that the machine `in view of theadjustable cams may be readily adjusted for many analogous purposeswherever perforations are desired.

Having thus described my invention, it is obvious that variousimmaterial modifications may be nia-de in the same Without departingfrom the spirit of my. invention; hence I do not wish to be understoodas limiting myself to the exact form, construction, arrangement andcomb-ination of parts herein shown and described, or uses mentioned.Vhat I claim as new and desire to sec-ure by Letters Patent is: tion bystop 87. vWhen the material Vabuts 1.
